It flows generally west from the White Mountains to the Tanana River near the city of Fairbanks, which is built on both sides of the river. The Tanana empties into the long Yukon River. Named tributaries of the Chena River include the North Fork, South Fork, West Fork, Middle (East) Fork and the Little Chena River.〔 The Chena River State Recreation Area surrounds much of the upper half of the main stem.〔 The Chena River is used for recreational fishing and boating.〔 During the winter months, it is also traveled by snowmachines and mushers (sled dogs). The Chena River Lakes Flood Control Project dam is about up the Chena River from Fairbanks. The dam was built in response to the 1967 Fairbanks flood, which inundated much of the city. When closed, the dam impounds water and, when the inflow is high enough, diverts it about to the Tanana River near North Pole, upstream of Fairbanks and the natural mouth of the Chena. ==Fish== The Chena River supports populations of many fish species, including Arctic grayling, burbot, chum salmon, humpback whitefish, king salmon, least cisco, longnose suckers, northern pike, round whitefish, and sheefish. Easily accessible from Fairbanks, the Chena is the most popular sport-fishing river in interior Alaska.〔 Overfishing for grayling reduced their number in the Chena to "dangerous levels" by the mid-1980s. In the 21st century, sport fishing for grayling, which grow in length to in the upper river, is limited to catch and release.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chena River」の詳細全文を読む スポンサード リンク
